LAM P Cl'lillllblEY GUIDE.

i's'ffififlltlijfiditltlfillhl' forming part of Letters Patent No.667,964, dated February 12, 1901.

Application filed October 20,1900. Serial No. 33,729- (No model.)

To all wlwnt if; may concern:

Be it known that I, FRITZ ALrtmNN, a citizen of the Empire of Germany,residing in Berlin, Germany, have invented certain new and usefulImprovements in Lamp-Chimney Guides, of which the following is aspecification.

In the usual devices for enabling chimneys of incandescent gas-burnersto be easily replaced there is between the parts guiding the chimney andthe crown of the burner a want of space for the tongues of the burner,the consequence being that a reintroduction of the chimney is diiiicultand liable to cause damage to the incandescent mantle. This inventionrelates to a device by which this disadvantage is overcome; and theinvention consists of a lamp-chimney guide comprising a protective tubeadapted to permit passage of the chimney through the same and springactuated clamps pivoted to said tube and extending beyond the lower endof the same for engaging the lamp-burner.

The invention consists, further, in the combination, with a lamp-burnerhaving tongues for engaging the lamp-chimney, of a lampchimney guideconsisting of a protective tube adapted to permit passage of the chimneythrough the same and spring-actuated clamps pivoted to said tube andextending to such length beyond the lower end of the same as to supportsaid tube above the tongues when the clamps engage the burner.

In the accompanying drawings,which illustrate a device embodying myinvention, Figure 1 is a vertical section through the device. Fig. 2 isa top view, and Fig. 3 is an elevation on a smaller scale.

Similar letters of reference indicate corresponding parts.

The tube 0, is secured to the burner-gallery d by means of clampsactuated by springs c.

' The lever-arms Z) of the clamps are pivoted to projections on thetubular guide a. The lower ends of the lever-arms are provided withcurved strips g, which engage the burnergallery when the device isapplied to the burner. The protective tube a may be made of any desiredmaterial. Two or more clamps may be employed, actuated by springs c,arranged as shown or in any other suitable mannerso that the clampsengage at several points on the burner-gallery and hold the tubularguide uniformly,

Between the lower edge of the tube a and the upwardly-projecting tonguesof the burnergallery is a space, so that the tube a does not come incontact with the tongues of the burner, and they are left free to engagethe chimney.

The operation of the device is as follows: Nhen it is desired to removethe chimney e, the tube a is placed over the chimney and moved downward,the levers Z) I) being pressed at their upper ends inwardly, wherebytheir curved lower portions are opened outward, so that they pass overthe burner-gallery and then grip the outside of the gallery. The chimneyis then removed by hand, the guide remaining clamped to the gallery. Thechimney is guided by the tube during the removal, and no injury to theincandescent mantle is possible. After the chimney has been cleaned itis replaced in the same manner through the tube a.

In case any of the tongues of the burner should become bent, so that thechimney catches between them when being replaced, the chimney is thenraised, and as the tongues are free and not in contact with the tube athey can be readily bent back into correct position, so as to permit thechimney to be reintroduced into its correct position.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A lamp-chimney guide, consisting of a protectivetube adapted to permit passage of the chimney through the same, andspringactuated clamps pivoted to said tube and extending beyond thelower end of the same for engaging the lampburner, substantially as setforth.

2. The combination, with a lamp-burner having tongues for engaging thelamp-chimney, of a lamp-chimney guide, consisting of a protective tubeadapted to permit passage of the chimney through the same, andspringactuat-ed clamps pivoted to said tube and extending to such lengthbeyond the lower end of the same as to support said tube above thetongues when the clamps engage the burner, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in presence of two subscribing witnesses.

FRITZ ALTMANN.
